dmidecode

操作概述

dmidecode 命令，读取并展示 DMI/SMBIOS 硬件信息（只读，禁止把 DMI 数据转储为文件）。

命令参数

禁止参数清单（命中即拒绝，含 GNU 唯一前缀缩写）：

-u|--dump            禁止参数，把 DMI 数据转储为二进制文件（写操作），拒绝执行
--dump-bin=<file>    禁止参数，把 DMI 数据转储为二进制文件（写操作），拒绝执行；
                     因 GNU getopt 支持唯一前缀缩写，--du 开头的写法（--du / --dum / --dump）同样命中拒绝；
                     注意 --dev-mem 不受影响（其最短唯一前缀为 --de）

使用示例

acli system dmidecode
